摘要: ‘春星’草莓果实成熟时,总糖和花青苷含量增加,呼吸速率也显著升高;同时,细胞溶质Ca2+-ATPase活性和微粒体膜的Ca2+-ATPase总活性变化具有相似的特点,即先升高,至粉红期达到高峰,全红期又下降,在微粒体膜中以质膜Ca2+-ATPase占的比例最高。抑制质膜Ca2+-ATPase活性的Na3VO4能促进草莓果实花青苷积累、降低可溶性总糖含量,但对呼吸速率的影响则因草莓果实成熟度不同而异。

Abstract: During strawberry (Fragaria ananassa Duch cv.chunxing)fruits maturation,the content of total sugar,anthocyanin and respiration rate increased significantly,and Ca2+-ATPase activity of cytoplasm and microsome membrane increased firstly,then peaked at pink stage,and decreased at full red stage in fruits,and also,the activity of plasma membrane Ca2+-ATPase was the highest in microsome membranes. Na3VO4,an inhibitor of plasma membrane Ca2+-ATPase activity,stimulated accumulation of anthocyanin,declined the total sugar content,but had different effects with various fruit mature degree.
